not transparent to X-rays or other forms of radiation; "barium sulfate is radiopaque"
Not allowing the passage of X-rays, gamma rays, or other forms of radiant energy.
not permitting the passage of x-rays, therefore visible on an x-ray image.
impenetrable to X-rays; appear as a light area on a radiograph
The white or clear appearance in a radiograph that results from the inability of radiant energy to pass through a structure. The more dense the structure (i.e., amalgam restorations), the whiter it appears in the radiograph.
Anything that does not let X-rays or other types of radiation penetrate. Radiopaque objects block radiation. They are opaque to radiation. See the entire definition of Radiopaque
Blocking the passage of X-rays and other forms of electromagnetic radiation.
something that is visible on plain x-rays, such as calcium stones
Opaque to x-ray radiation and thus visible on x-ray film.
an object/item/mass that appears on a radiograph that does not allow the x-ray to pass through it when in normal circumstances it would, (eg. a bone that looks more dense than the bones around it)
